In a world where Art is magic, lives a girl named Sakurai Shirogane. She has a cold personality that some believe is the cause of her oddly shaped sparkles. Snowflakes. After her father died, Sakurai lost her warm smiles and gained bitter smirks as well as altering her sparkles as she continued to fall deeper into her music in attempt to escape reality. Now, she's attending Hoshinomori Private Magical Arts High School as a first-year, hoping her school years will go by in a blink, but her hope shatters once she is informed that she was chosen as part of the committee for the Hoshinomori Summer Festa cultural festival.
